Abstract
The present invention provides a liquid crystal display device having a matrix electrode structure in which an image elimination period for rewriting a display is shortened without sacrificing the display brightness, while suppressing flicker, a ghost image and a cross-talk on the display. In the eliminating period, a pulse voltage having a polarity opposite to that of a holding voltage imposed in an image holding period preceding the selecting period is applied to scanning electrodes, and then a lower level standard voltage is applied. The pulse voltage may be in a form of one or more bipolar pulses having a pair of pulses with opposite polarities. The eliminating period for rewriting the display is considerably shortened according to the present invention.
